'irrigator' originates from Latin, specifically the word 'irrigare,' where 'ir-' meant 'in' and 'rigare' meant 'to water.'

'irrigare' transformed into the French word 'irriguer,' and eventually became the modern English word 'irrigate,' from which 'irrigator' is derived.

Initially, it meant 'to water or moisten,' but over time it evolved into its current meaning of 'a person or device that waters crops.'
